I really like this pen; it's a good weight, and it does indeed write perfectly well upside-down.

Loved this pen. Worked great as a "leave in the car" emergency pen...until it decided to vacuum seal itself shut! Can't get enough grip to open it. Star was docked for this reason only.

This pen is a delightful surprise! I was in search of a small jotter pen to take the place of my Parker Jotter which I never loved but was convenient to have during my travels. Love the green! Its weight is satisfactory. Its compact size pairs nicely with the passport-sized Traveler's Notebook or any small memo writing pad. When the cap is posted, it becomes an average sized pen which is terrific. The Fisher Space ink cartridge is decent and writes well. I purchased two items which upgraded this pen for me: (1) the Fisher Space Bullet pen clip in chrome to match the pen's silver colored grip section and (2) the Zebra JK gel refill (some of the refill's plastic end needs to be clipped off to get it to a perfect length). I plan to purchase a couple more. I recommend this item.

The anticipation to get this pen in the mail was high, and it did not disappoint. It is actually super tiny, which I wasn't expecting, but it adds to the charm. Great packaging. The pen writes smoothly and without faltering--in water and on a normal surface.

My youngest son has always loved pens but since childhood would lose them immediately. I had gotten him one of these before but of course he lost it - now he is 24. Hopefully he can hang on to it for a bit!

Excellent!! Just as I hoped!

I bought this pen as a gift for my girlfriend and she loves it so much. The bright green is one of her favorite colors and she uses the pen daily. It writes well and is perfectly pocket sized.

A lovely little pen that Just Works.
